Application led September 26, 1908. i Serial No. 454,871.

' resident of St. Louis, Missouri, have invented certain new and usefulImprovements in Automatic Intermittent Flushing-Valves', of which thefollowing is a specification. containing a full, clear, and exactdescription, reference being had to the accompanying drawings, forming`a part hereof.

My invention relates generally to a valve, and more particularly to anautomatic intermittent lushlng valve, particularly intended' for use inconnection with water supply pipes of closet bowls, and the object of myinvention is to rovide a sim le inexpensive valve which wilautomatically and intermittently open to allow water to dischargethrough the sup ly pi e, and said valve being provided wit simp e meanswhereby the intermittent action can be accurately regulated, and theeriod of flushing accurately timed., i

To the above purpose my invention consists in certain novel features ofconstruction and arrangement of parts, which will hereinafter be morefully set forth, pointed out in the claims, and illustrated in theaccompanyingvdrawings in which 1 igure 1 is a front elevation of a valveof my improved construction, the same being shown inposition for use.Fig. 2 is an enlarged vertical section taken from the center of my imroved valve.

section ta enon the line3-3 of Fig. 2. Fig. 4 1s aside elevation partlyin section of a modified form of my lmproved valve.

The housing of my improved valve is constructed in two main portions, 1designating the rear portion, cularchamber 2, and` formed integral withthe front of this portion 1 is a narrow vertically disposed housing 3,in which is formed chamber 4, and iixed to the front wallof the portion1, and separating. the chambers 2 and 4, is a diaphragm 5. Formedintegral wlth the upper end of the housing 3 is' a tubular extension 6,which is adapted v to be connected to the water su ply pipe 7, andformed in the wall of the ousing 3, immediately "beneath this extensionis a conical opening 8 whichd is normally closed b a conical valve 9..Detachahly positione inv the upper end of the tubular extension 6, is aperforated plate or spider 10 provided with a depending pin 11 whichyenters a corre.-

't e purpose of guiding said valve Fig. 3 is a verticalV .ranged on `endof a corresponding link 28, the up of which latter is pivotally connecteand formed herein' is a c1rare formed integra wit s onding apertureformed in the valve 9, for during its vertlcal movement and arranged onsaid pin between the valve and the perforated plate 10 is an expansivecoil spring.12. A passage way 13- establishes communication between thechamber 2 and the chamber within the tubular extension 6; and seated inthe wall of thei housing 3 is a regulating screw 14 which is adapted toclose this assage way. Formed through the wall inwhich the valve seat 8is formed and establishing communica- 'tion between said valve seat oropening 8 andthe passage way 13 isa assage way 15 and screw seated inthe wa in which this passage way is formed is a regulating screw 16 theforward end of which is adapted to close said passage way 15.

Fixed to the center of the diaphragm 5 is a horizontally dis osed pin 17on which is formed a pair of ugs 18 and 19, and the forward end of saidpin is seated in an aperture formed in the rear end of a screw 20, whichlatter is seated in the front wall of the housing 3. Located upon theinner end of this screw '20 and bearing against a disk 21 carried b thepin 17 is an expansive coilspring vertically/disposed lever 23 isfulcrumed upon a in 24 which latter is iixed in the side walls o thehousing 3 and the upper end of said lever is rovided with a air of lugs25 and 26.. A ink 27 is ivota 1y arthe pin 24 which lin passes betweenthe lugs 25 and 26 and the upper end of this link is pivotally connectedto the lower er end to the bottom of the valve 9.

29 designates a pivot bottonrof the housing 3 direct vertical alinementwith the pin 24, and the center of the valve i9; arrangedto rock on thesaid pivot point is the lower end of a tube 30, 41n

point formed on the theupper portion of which is arranged to,

slide a 'pin 31, the upper end of which pivotallyv engages the lower endof the lever 23. Arranged on said tube 30 and in 31 and bearing againstshoulders forme thereon is an expansive coils rin 32. Lugs 33 and 34 oneof the side walls of the housing 3 beneath the pin 17, which lugs formstops to limit the swin of the lever 23; yfo'rme'd integral with one of51e side walls ofv the housing 3 is a lug 35 which forms a stop tolimit-the movement in one direction ric' l way 13 into the chamber 2,it-being underis forced upward through the passage way 13,

stood that the regulating screw 14 is set so as to 'permit water todischargethrough said passage way 13. The pressure of the water withinchambe'r 2 acts upon diaphragm 5 and slowly moves the. same toward' thechamber 4 which action 'shifts the pin 17 toward the screw 20, thuscompressing the s ring 22, and at the same time causing the liig 18 tobear against one side of the lever 23, .and as l this movement continuessaid lever with its lower end bearing on the pin 31 is gradually movedinto a vertical position, and as soon as.

the pivot point between the lower end of the said lever and pin 31passes the center, the power stored' in the coil spring 32 willvinstantly act to swing the lower ortion of the lever 23 over against thesto ug 34, and as this movement takes place t e lug 26 on the upper endof said lever .will bear against the correspondin side of the link 27thus movlng the said k and link 28 into approximately verticalalinement, which action elevates and unseats the valve 9. The pivotpoint between thetoggle links 27 and 28 during this action movesslightly past the center or until the link 28 rests against the-stop lu35 and thus the valve 9 is held in an unseate position, and the waterfrom the supply pi e is n ow fr e to pass downward through t e conicalopening 8 mto the chamber 4, whence it dischar es through the outletpipe 36. A's

soon as va ve 9 is unseated the pressure in the chamber 2 1s relievedand the water therein owing to t e return of the diaphragm 5 to itsnormal posltion, which action is brought about by the expansion of thespring 22, and as this movement takes place the lu 19,\car ried by pm17, will engage against t e correspondmg side of the lever 23, and saidlever will be gradually moved into a vertical positlon, and as the pivotpoint between said le'- .ver and pin31 passes the center, the powerstored in the spring 32 will act to throwsaid lever mto the positionshown in Fig. 2; and as this movement takes place the lug 25 will bearagainstthe corresponding side of link 27, thus shifting the link, and inturn moving thepivot point between the links 27 and 28 past the centerand as a result the power stored in spring 12 will act to reseat andclose valve 9.

During the time the valve is elevated the In a modiiied form of thedevice seen in I Fig. 4 the toggle links 27 and 28 are dis` pensed withand a trigger37 is ivotally carried by the upper end of the ever 23; andwhich trigger is adapted to engage pin 38 carried by the valve 9.

A device of my .construction is sim le, inexpensive, and can beadvantageous y employed in connection with any apparatus wherein anautomatic and intermittent discharge of fluid is desired.
